Yes but hosting a “free speech instance” in a country without freedom of speech protections will be harder to run due to the lack free speech rights. I advise running such an instance in the US for this reason.

The users on the instance that are not US citizens have to in theory follow their local laws. Kinda like how a Russian or Chinese internet user needs to be cautious when using American social media.

If your going to run a free speech instance, I advise running the server in the US and using a server provider that is free speech friendly. It will also not hurt to use a domain registrar that is pro free speech. By running the server in the US, you got first amendment protection
